The results of a study of active oral hygiene treatment in children between the ages of 4 and 12 was reported. It is absolutely imperative that both the children and the parents be highly motivated to carry out consistant oral hygiene. The basic level of oral hygiene for children can be considerably improved if the children are instructed in the appropiate technique for tooth brushing and allowed to practice; the children should be regularly checked by the dentist.

A double blind trial was undertaken to determine whether the addition of the beta-receptor blocker Betadrenol in two different doses to a lidocaine solution containing adrenaline could influence the exogenous and endogenous beta-adrenergic effects in the field of dental interventions under local anesthesia. It could be shown that already very small amounts of the beta-receptor blocker Betadrenol could suspend beta-adrenergic stimulation of the heart and so prevent unwanted circulatory reactions without side effects on the central nervous system.
The dentitions of 146 children with cerebral palsy showed a high incidence of gnathic anomalies. There was, however, no relation between these anomalies and the severity of the neuropathological findings. Also the total number of anomalies was almost evenly distributed among the various clinical pictures such as spasticity, athetosis, ataxia. Although combinations of the individual anomalies were found most frequently, marked protrusions of the upper jaw were particularly impressive with 55%, and were followed by class II malformations (47%). In addition, almost every third tested child had an open bite.
